A WHEEL

He had thought that he would get a good haul of worlds under his reign this time and instead he had found a world where its inhabitants are not only powerful and possess magical power, it is also protected by a powerful invisible force that surpass the protection of the withering Seresian world.

And it is not only one treasure that is hidden inside this world. There are two treasures. The first thing he realizes was that this world is full of energy. 

And this energy is unlike any other. It is limitless.

It bestows luck and fortune. 

Luck and fortune when it reached the pinnacle, it has to be offset with disasters. When one overcome the disaster than luck and fortune would come in double

It is the principle of whatever doesn't kill you, makes you stronger.

And the luck and fortune that have weathered tribulation become harder to shake and it is not only illusory as it become sold and tis luck would keep on giving.
